DRAFT ATTACHMENT FOR CULTIVATOES.

Specification of Letters Patent.

Patented June 9, 1914 Application filed November 18, 1913. Serial No.801,704.

To all whom it may concern:

Be it known that I, ELAN Porn, a citizen of the United States, residingat Tulia, in the county of Swisher and State of Texas, have invented newand useful Improvements in Draft Attachments for Cultivators, of whichthe following is a specification.

This invention relates to draft attachments for cultivators andespecially for tworow cultivators of the type commercially known as theCanton and other cultivators of the same general type.

The invention has for its object to pro duce a draft attachment enablingfour or five horses to be used, and including eveners whereby the draftwill be equalized.

A further object of the invention is to produce a construction includinga drop hitch whereby the weight of the tongue will be removed from thenecks of the draft animals, the draft being upward rather than downward.

A further object of the invention is to produce a simple and improveddraft attachment Which may be readily appliedto and used in connectionwith the conventional cultivator without altering the construction ofthe latter.

lVith these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings,-I igure 1 is a front elevation of a draft attachmentconstructed in accordance with the invention. Fig. 2 i a f I of thecross bar 19 is a yoke 35. ends of the drop links 29 are connected bytop plan view of the same. Fig. 3 is a side elevation. Fig. 4 is a rearelevation. Fig. 5 is av top plan View illustrating a modification. Fig.6 is a perspective detail view of one of the hitching brackets andrelated parts. Fig. 7 is a perspective detail view of the drop link andthe clevis carried thereby.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The conventional arched axle 15 is supported on the ground Wheels 16.Connected wlth the axle by means including the hounds 0r braces 17 arethe thills or tongue members 18. A cross bar 19 extending beneath thetongues is supported by means of clips 20 that straddle the hounds.

flight and left brackets 20 are mounted adJa n to the outer faces of thetongue members, the rear ends of said brackets abutting on the axle, andsaid brackets being secured near their rear ends by means of bolts 21engaging the hound members 17. The brackets 20 are also secured by meansof clips 22 engaging the cross bar 19, and

said brackets include arms 23 that extend laterally and outwardly fromthe forward ends thereof, said arms having rearward extensions 2e.Hook-shaped brackets 25 are secured on the rear face of the axleadiacent to the ends thereof, said hook-shaped brackets being curvedrearwardly of the wheels 16, and said brackets being connected by bracerods 26 with the ends of the extension portions 24 of the brackets 20.

Pivotally connected with the arm 23 of each bracket 20 is a lever 13having an inwardly extending relatively long arm 27 and an outwardlyextending relatively short arm 28 with which latter an evener 29 isconnected, J said evener being in the nature of a doubletree having droplinks 30 comiected with the ends thereof. Connected pivotally with thelong arm 27 of each lever B is the upper end of a drop link 29". Thedrop links '29 are each provided with a series of aper tures 30' for thepassage of a bolt 31 supporting the clevis 32, the two clevises 32serving to support a cross bar 33 with which a whitlietree is connected.The whiffletree 34 is utilized only when five draft animals walkingabreast are used, when one of the animals will be placed between thetongues 18, a double team being hitched outside of each tongue.

Secured oneach of the tongues 18 in rear The lower flexible elements,such as chains 36, with the downwardly extending inner limbs of the atthe inner ends of the doubletrees 29.

The drop links 30 at the outer ends of said doubletrees are connected bychain 38 with tioned to take into account the fact that the one animalwalking between the tongues has to pull against the four animals walkingoutside of the tongues. When it is desired to use only four draftanimals, the one walking in the middle is dispensed with, and the innerends of the inwardly extending long arms 27 of the levers B areconnected together by arigid brace member 41 secured thereon by means ofbolts 42, as seen in Fig. 5. A similar brace member 41 may be used toconnect together the inner ends of the yokes 35, or said inner ends maybe secured in any convenient manner so that the stay chains 37 wvill beeffective when the middle swingletree is dispensed with, as in Fig. 5.The levers B, B will thus be converted into what practically constitutesa single rigid cross bar with the ends of which the doubletrees 29 areconnected. The peculiarly constructed brackets 20 and yoke 35 permit theuseof the drop links 30 and 29, the lower ends of which are connectedwith the downwardly projecting stubs 39 of the brackets and with thedownwardly extending limbs of the yokes, by means of flexible elements,such as chains, whereby the draft is properly transmitted in such amanner that an upward rather than a downward strain will be exerted, andthe necks of the draft animals will be relieved of undue weight.

' The general construction of the improved attachment is simple andinexpensive, and it is of such a nature that it may be readily appliedto two row cultivators of conventional construction, the arrangementbeing such that the plants will be cleared by the attachment and thatthe draft animals will be placed between the rows of plants.

Having thus described the invention, what is claimed as new, is

1. The combination with a two-row cultivator having an arched axle, andtongues provided with hounds connected with said axle, of bracketsabutting on the axle and secured on the hounds near their rear ends, across bar supported by the hounds and supporting the brackets near theirfront ends,

i said brackets including lateral arms having rearward extensionsprovided with terminal downwardly projecting stubs, and draft meansincluding eveners having drop links, yokes secured on the tongues andhaving downwardly extending limbs, flexible elements connecting the droplinks with the yokes and with the stubs of the brackets, andswingletrees connected with the drop links.

2. A draft attachment for two-row cultivators comprising brackets havinglateral arms with rearward extensions provided with downwardlyprojecting stubs, means for supporting said brackets adjacent thecultivator tongues with their rear ends abutting on the axle, yokesstraddling the tongues, levers fulcrumed on the lateral arms of thebrackets, drop links connected with the inwardly extending long arms ofthe levers, chains connecting the lower ends of the drop links with theinner limbs of the yokes, a cross bar connecting the drop links andhaving a whiffletree, eveners connected with the outwardly extendingshort arms of the lovers, drop links at the ends of the eveners, chainsconnecting the lower ends of the drop links at the inner ends of theeveners with the outer limbs of the yokes, chains connecting the lowerends of the drop links at the outer ends of the eveners with thedepending stubs of the brackets, and whiflletrees connected with thedrop links at the ends of the eveners.

3. The combination with a two-row cultivator having an arched axle andtongues, of

a draft attachment comprising forwardly extending brackets abutting onthe axle and including lateral arms having rearward extensions providedwith downwardly projecting stubs, hook-shaped brackets secured on therear side of the axle, means for supporting the first mentioned bracketsincluding a cross bar extending beneath the tongue, braces connectingthe hook-shaped brackets with the rearward extensions of the forwardlyextending brackets, yokes straddling the tongues, levers fulcrumed onCopies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents,
